Question
if a = 120°, find each: b = type your answer... c = type your answer... d = type your answer... e = type your answer... f = type your answer... g = type your answer... h = type your answer...
Step1: Ángulos opuestos por el vértice
Los ángulos opuestos por el vértice son iguales. Entonces, $a = d = 120^{\circ}$ y $b = c$. Además, $e = h$ y $f = g$.
Step2: Ángulos adyacentes suplementarios
$a + b=180^{\circ}$ ya que son adyacentes y suplementarios. Dado que $a = 120^{\circ}$, entonces $b=180 - 120=60^{\circ}$. Entonces $c = b = 60^{\circ}$.
Step3: Ángulos correspondientes
Si se asume que $m\parallel n$, entonces los ángulos correspondientes son iguales. Entonces $a = e = 120^{\circ}$, $b = f = 60^{\circ}$, $c = g = 60^{\circ}$ y $d = h = 120^{\circ}$.
